Abstract (en)
[origin: WO2017206941A1] A portable odor detector (100) and an operating method thereof are provided. The detector (100), especially for a disposable hygiene product or its raw materials, comprises a housing (200), a display screen (300), a battery assembly (700), a circuit board (500) and a sampling unit (600). The sampling unit (600) comprises a heat-resistant housing (610), and an odor sensor (651) is arranged in a detection chamber (630) in the housing. A test airflow can be sucked into the detection chamber (600) by an air pump (800) through an airflow sampling passage (660) and then discharged out through an airflow returning passage (670). The odor sensor (651) can heat the airflow so as to decompose gas molecules into charged ions which can be converted to electrical signals, and the signals can be transmitted to the circuit board (500) for storage and/or displayed on the display screen (300).
